==Epidemiology==
Sarcomas are rare cancers.<ref name=":1" /> The risk of a previously healthy person receiving a new diagnosis of bone cancer is less than 0.001%, while the risk of receiving a new diagnosis of soft-tissue sarcoma is between 0.0014 and 0.005%.<ref name=":2" /> The American Cancer Society estimates that in the United States there will be 3,970 new cases of bone sarcoma in 2023, and 13,400 new cases of soft-tissue sarcoma.<ref name=":7" /> Considering that the total estimated number of new cancer diagnoses (all types of cancer) is 1,958,310, this means bone sarcomas represent only 0.2% of all new cancer diagnoses (making them the 30th most common type of cancer<ref name=":8" />) and soft-tissue sarcomas represent only 0.7% (making them the 22nd most common type of cancer<ref name=":9" />) of all new cancer diagnoses in the US in 2023.<ref name=":7" /> These estimates are similar to previously reported data.<ref name=":2" />

Sarcomas affect people of all ages. Around 50% of bone sarcomas and 20% of soft-tissue sarcomas are diagnosed in people under the age of 35.<ref>{{cite journal |vauthors=Darling J |title=A Different View of Sarcoma Statistics |journal=ESUN |volume=4 |issue=6 |year=2007 |url=http://sarcomahelp.org/articles/sarcoma-statistics.html |access-date=2012-10-06 |archive-date=25 July 2013 |archive-url=https://web.archive.org/web/20130725060105/http://sarcomahelp.org/articles/sarcoma-statistics.html |url-status=dead }}</ref> Some sarcomas, such as [[leiomyosarcoma]], [[chondrosarcoma]], and [[gastrointestinal stromal tumor]] (GIST), are more common in adults than in children.<ref name=":1" /> Most high-grade bone sarcomas, including [[Ewing's sarcoma|Ewing sarcoma]] and [[osteosarcoma]], are much more common in children and young adults.<ref name=":1" />
